After entering the dungeon, the green vines all over the world disappear, and inside the dungeon is a normal map of ruins. The first tower was unusually dilapidated and old, with a hint of moss visible at the entrance, but further into the dungeon, the moss stopped growing, as if it had been blocked by some kind of force.

"The Ancient Library." Xia Chiyu replied that they divided into two teams according to the previous plan before entering the book and began to explore this map. The first floor was empty, there weren't many monsters, just a few geyers.

The monsters in this dungeon are level eighty monsters, and they are ten people difficult, so it is not easy for Xia Chiyu and Reis to deal with, but fortunately, the members of the team are all members of Karazan who have cleared the wasteland together, and there is no problem with the cooperation.

Xia Chiyu and Lacey have made up for the level gap of others, and now they are also top PVE guilds, and their strength and equipment far exceed that of ordinary players. With the cooperation of everyone, it can be regarded as a smooth cleanup of the monsters on the first layer.

Immediately, the magical glow at the entrance to the second floor dissipated, and they descended the stairs to the second floor. The second floor already took on the appearance of a library, where rows of bookcases were placed, but there were not many books left on the bookcases, and a large number of parchment scrolls were scattered on the floor, which had turned black and brown from the damp due to their old age.

In the history of AO, the Ancient Library was once a gathering of "ancient human civilizations", where the world's best wise men gathered, and were the embodiment of human wisdom. Until one day, one of the three empires coveted the knowledge in the ancient library and launched an attack, they tried to take the wisdom of the ancient library and use it to develop the empire's military power.

It was a war of wisdom and force, and the Ancient Library had all kinds of magical magic, but in the end, it was defeated by the iron and blood of the Empire, and the Imperial army rushed into the Ancient Library, plundering and destroying the civilization here. But at the last minute, the library's director unleashed the library's last magic.

No one knows what happened after that. The history books only say that the imperial army eventually retreated.

After Xia Chiyu and the others came to the second layer, the two stone guards on the edge of this layer trembled, and then the crack spread rapidly from their surface, and golden light emerged from under the crack. Immediately, the two stone guards turned into two winged guards in golden armor, and the name "Guardian of the Ancient Kings" emerged from above them.

"The eighty-level boss is actually a divine creature...... Xia Chiyu said to himself in surprise. The so-called divine creatures in AO mean that they are sacred creatures such as angels and gods, who are good at light-based magic, resistant to light-based magic, and are the antithesis of evil creatures such as demons and undead. Attack them with a dark element, giving them a damage bonus.

Divine creatures are rare in AO, and unlike the undead and demons, divine creatures have almost no low-level creatures, are generally above level seventy, and rarely act as enemies. I didn't expect to become a guard here......

"It's a little bad...... Xia Chiyu said with a dry smile, although there is no attribute of divine magic resistance in AO, divine creatures are born with up to fifty percent light magic damage reduction. And although Xia Chiyu has mastered multiple spells, the light system is still his main means of damage, and the other systems are just auxiliaries. Damage spells are also very monotonous and scarce.

"I knew that I would have teamed up with Su Xing...... Xia Chiyu thought secretly, but it was not impossible.

"Well, I have to remind you that divine creatures have a high damage reduction from light-based magic. So I'm going to be the only one to support in this battle, so you can attack. Xia Chiyu explained, "I will be responsible for assisting you as before. ”

The crowd responded, and then attacked the Ancient Kings Guard.

But. The Ancient Kings Guard is already a level 80 boss, and the AI of this level boss is very flexible, so it is obviously not so easy to deal with. Xia Chiyu hurriedly assisted everyone. This barely ensured that no one was seriously injured. But if it continues like this, sooner or later someone will make a bigger mistake, and Xia Chiyu can't save every one of them all the time.

"Lacey," Xia Chiyu shouted, waving his hand to summon a vine and dragging Li Feifei back, and the next moment an ancient king guard swung his sword and slashed at the area where Li Feifei was before, and a golden pillar of light rose from the location of the slash, "Shake off your shield, you are responsible for attacking and creating opportunities, they will be handed over to me first!" ”

"Got it!" Lacey answered, dropped the big shield, switched to the punisher state, and then raised his long sword, using the sacrificial judgment to help Liu Yiyu attack the next ancient king's guard, and used the royal counterattack to instantly pass over the ancient king's guard. The opponent immediately fell into a brief stun, while the others cooperated with Lacey to launch a follow-up attack.

However, since the boss has ten people's blood, even if Lacey is already level ninety, there is no way to simply continue to beat the ancient king's guard out of the follow-up hard stun, and although the HP of this small volume of the boss is small, it has a "forced detachment".

That is, after taking a certain amount of damage, it will enter a period of invincibility and be forced to get out of the state of being comboed. Everyone's attacks slammed into the guards of the ancient kings, knocking them out about ten percent of their health, and the other party immediately flapped his wings and flew back a few meters with agility, forcibly getting out of the hard straight state, and then flapped his wings again and quickly flew towards Cheng Ming.

Rey reacted extremely quickly, blocked in front of Cheng Ming, and swung his sword to block the sword guarded by the ancient kings, and several sparks burst out from the place where the swords met. But even if there is a level gap of ten levels, the boss is a boss after all, and Lacey is completely unable to defeat the opponent in terms of strength, and is pushed backwards to slide away.

Seeing this, Xia Chiyu hurriedly dragged Cheng Ming away, but there were two ancient guards on this floor, and Xia Chiyu also had to take care of the other ancient guard's team members and had no time to take care of it. A golden glow erupted from Lacey's body, and golden spells flashed from the surface of his armor, and his strength increased suddenly, halting his retreat.

Xia Chiyu knew that Lacey had used the passive domain skill, and the battle over there should not be a problem, so he temporarily shifted his attention to the ancient king's guards here.

He stretched out his hand and pressed it on the ground, and a steel gate blocked in front of the guards of the ancient kings and Xiao You, who immediately stepped back, "Bell! A bell rang, and a hole appeared in the steel door. Soon the ancient king split the Iron Gate in two and continued to attack, but with this block, Xiao Yu had already completed his spell.

"Spiral Ice Blast!" Xiao Yu aimed his staff at the Ancient Kings guard. A spiraling blizzard erupted, and the Ancient Kings Guard raised their shields in defense, and the entire shield was frozen into ice.

The guards of the ancient kings threw away the shield in their hands without hesitation, and attacked Xiaoyou again with the sword in both hands, at this time Zhang Zhiwei waved the big sword and rushed up, relying on the momentum of the charge and the guard of the ancient kings.

"Ping!" With a crisp sound, Zhang Zhiwei snorted and flew backwards, Xia Chiyu summoned a few vines to drag Xiao You back, and at the same time summoned a huge leaf to catch Zhang Zhiwei to avoid collision damage.

"Thanks, eat the fish." Xiao You thanked Xia Chiyu. Zhang Zhiwei slipped from the leaf and fell to the ground, hurriedly got up and rearranged the formation, and sighed: "What is the eighty-level BOSS, it's amazing......"

"yes, the AI is so high, it's like the player is behind it." Lin Qianxue frowned and said, "I didn't expect it...... You're actually fighting such monsters all the way up to level ninety. ”

"It's not all ......," Xia Chiyu raised his eyebrows and said, raising his hand to aim at the Ancient Kings Guard, and several thick vines rose from under the Ancient Kings Guard to entangle it. And Ye Ziyuan immediately saw the opportunity, and the dagger stabbed at the waist of the ancient king's guard. Due to the effects of the Assassin's Weakness Strike, the Ancient Kings Guard fell into a brief coma.

And while they were entangled with the Ancient King's guard, Lacey's side had already dealt with another Ancient King's guard. At this moment, he and the other two golden knights turned into three golden rays of light and swept past the ancient king's guard, and the three golden rays crossed to form a six-pointed star. And the follow-up attacks of the others followed.

Even so, it took a lot of trouble for them to deal with the two guards of the ancient kings. Xia Chiyu is the mage class with the highest attack power in the team. But he couldn't become the main attacker, which led to all the attack pressure accumulating on Lacey. Due to the advantage of passive domain skills and levels, Lacey's damage alone is comparable to that of the entire group.

"It's going to die. This is only the second layer, and the boss is so difficult to beat. Ye Ziyuan complained.

"yes, and from the outside, it's clear that this tower is much more than just a few floors." Pepe said as she looked up at the ceiling in annoyance.

"Don't worry, not every floor will be a boss." Xia Chiyu smiled bitterly and said, "These two ancient kings are already very troublesome to guard, but the strength alone should not be enough to sweep away the armies of the three major empires. So I think there's probably more trouble waiting for us. ”

"Something more troublesome than the Ancient Kings guard? Let's go back, guys, the dragon slaying weapon is still a little too hard for us. Zhang Zhiwei said with a dry smile.

"Don't be discouraged, let's take a look up first." Xia Chiyu said with a smile and led everyone to the third floor.

As Xia Chiyu said, what appeared after that were some elite monsters, most of them were dead dead soldiers, and there were also some magic traps, but they were all relatively easy to deal with. The situation above was basically the same as on the second floor, with a library full of bookcases and old and broken parchment scrolls scattered all over the place. On the sixth floor, four Ancient Kings appeared.

"Is it too late for us to retreat?" Zhang Zinuo hid behind Xia Chiyu and asked in a whisper, Xia Chiyu raised his eyebrows and muttered, "It's too late, but I don't want to go back like this." ”

With that, Xia Chiyu turned to Lacey and asked, "How is it, what do you think?" ”

Lacey shook his head: "I'm going to recover a bit, and if I can, I'd like to save the skill for the last boss layer." ”

"Okay, then let me do it." Xia Chiyu said, exuding a terrifying elemental brilliance around him. He crouched on the ground, and the various colors of light quickly condensed, emitting a light like thunder and lightning, and then formed nine dragons.

"Nine Dragon Array......" Xia Chiyu said in a low voice, in the case of light magic not working, he can only rely on the Nine Dragons Formation that his skills use once to cause damage to these four bosses. If you want to kill these four bosses in seconds, Xia Chiyu can't do it, after all, he is already level ninety, and there is enough level difference, but this requires the use of forbidden spell-level spells.

"Fire, wind, metal, earth...... Xia Chiyu whispered, "The two monsters were separated on that day, the female was called Leviathan, and it dwelt in the abyss of the fountain; The male is called Behemoth, and it occupies the entire desert ......"

"Devouring of Behemoth!" Xia Chiyu shouted, the dark red dragon symbolizing the flame element, the yellow dragon symbolizing the earth element, the cyan dragon symbolizing the wind element, and the orange dragon symbolizing the metal element were entwined and intersected, and then merged into the ground. The ground beneath the feet of the four ancient kings instantly turned into sand and rose, condensing into a monstrous maw that swallowed them.

Then, the sand solidified and contracted, and the four guards of the Ancient Kings struggled out from under the sand, and two of them reached out and pressed their hands to the edge of the floor, but by this time the sand that had devoured their bodies had solidified like cement, and the bodies of the four guards of the Ancient Kings trembled, and the sand emitted a golden light.

It was clear that the bodies of the Ancient Kings' guards in the sand had been completely crushed. The health of the four Ancient Kings guards and Xia Chiyu's mana quickly decreased, and the four Ancient Kings guards were directly killed in seconds, and Xia Chiyu's mana was only less than one-third. The forbidden spell under the effect of the Nine Dragons Array consumes more mana than the ordinary forbidden spell.

However, this effect is obviously very good, and four level 80 boss-level monsters were eliminated in one hit.

Actually, Behemoth's Devour is a judgment spell, meaning that it doesn't deal damage until it hits, and it doesn't deal any damage if it doesn't, but it still consumes mana. In this way, after the balance of the comprehensive value of the skill, it will cause more terrifying damage, so this effect can be achieved.

It just so happened that the Ancient Kings guarded this kind of monster, it would not move until it was triggered, and it would stand in place until the player stepped forward to trigger, so Xia Chiyu used this to maximize the power of the judgment forbidden spell. The reality is that not all forbidden spells can hit bosses so easily, especially agile bosses of this small size.

Behemoth's Eater corresponded to Leviathan's roar, and Leviathan's roar had been used by enemy members in the arena in the past, but with the blessing of the Nine Dragons, the forbidden spell was even more powerful. It can be seen that the chanting of the two forbidden spells is almost the same, but the order is reversed.

"Amazing...... Awesome, awesome! I actually put these four bosses in one breath! Ye Ziyuan couldn't help but sigh, then slapped Xia Chiyu on the shoulder, and said with a smile: "It's worthy of eating fish!" ”

"yes, but I'm completely ruined." Xia Chiyu smiled dryly, "It's up to you." (To be continued......)
